AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OR
830 PM PDT THU JUN 2 2011

.UPDATE...A TROUGH OF LOW PRESSURE WILL GRADUALLY MOVE OUT OF THE
AREA TONIGHT. PRECIPITATION HAS DECREASED ACROSS THE REGION WITH
ISOLATED SHOWERS REMAINING OVER THE COLUMBIA BASIN AND EAST INTO THE
BLUE MOUNTAINS. EXPECT THESE SHOWERS TO CONTINUE TO DISSIPATE AFTER
SUNSET. WITH AN END TO THE SIGNIFICANT RAINFALL...HAVE BEEN EXPIRING
THE FLOOD WARNING AND FLOOD ADVISORIES ACROSS NORTHEAST OREGON AND
SOUTHEAST WASHINGTON. MANY OF THE CREEKS AND STREAMS WILL REMAIN
HIGH...BUT WILL BE CRESTING IN THE NEXT 24 HOURS AS DRY CONDITIONS
MOVE INTO THE REGION. THE JOHN DAY RIVER AT SERVICE CREEK
HOWEVER...WILL CONTINUE TO SEE A RISE AS SNOW MELT UPSTREAM AND THE
HEAVY RAIN WORK ITS WAY DOWNSTREAM. WILL BE ISSUING A FLOOD WARNING
FOR THE JOHN DAY RIVER AT SERVICE CREEK AS THE RIVER IS FORECAST TO
GO ABOVE FLOOD STAGE FRIDAY MORNING. PRESSURE GRADIENTS ARE
DECREASING ACROSS THE AREA AND WILL SEE WINDS DECREASE OVERNIGHT.
HAVE ALLOWED THE WIND ADVISORY FOR THE KITTITAS VALLEY
EXPIRE...THOUGH BREEZY CONDITIONS CAN STILL BE EXPECTED OVERNIGHT.

.AVIATION...PREVIOUS FORECAST...00Z TAFS...AN AREA OF RAIN OVER THE
LOWER COLUMBIA BASIN AND BLUE MTN FOOTHILLS CONTINUES TO IMPACT KALW
WITH SHOWERS NEAR KPSC AND KPDT. PRECIPITATION SHOULD TAPER OFF
LATER THIS EVENING. VFR CONDITIONS ARE GENERALLY EXPECTED BUT MVFR
CEILINGS WILL BE POSSIBLE AT KALW. SKIES WILL BECOME MOSTLY CLEAR ON
FRIDAY. WINDS WILL RANGE FROM 10-20 KNOTS THROUGH THIS EVENING THEN
WILL DIMINISH OVERNIGHT. WINDS WILL REMAIN LIGHT ON FRIDAY..EXCEPT
AT KRDM AND KBDN WHERE WINDS WILL INCREASE DURING THE AFTERNOON TO
10-15 KTS.  82

.PREV DISCUSSION... /ISSUED 412 PM PDT THU JUN 2 2011/

SHORT TERM...TONIGHT THROUGH SUNDAY...UPPER LEVEL LOW CONTINUES TO
SLOWLY EXIT THE REGION. MAIN PRECIPITATION CONTINUES TO BE OVER
NORTHEAST OREGON AND SOUTHEAST WASHINGTON THIS AFTERNOON BUT RADAR
AND SATELLITE SHOW PRECIPITATION IS TRENDING DOWNWARD. THIS WILL
LEAD TO DECREASING SHOWERS IN THE FORECAST FOR THIS EVENING AND
OVERNIGHT. DO EXPECT ALL SHOWERS TO COME TO AN END BY LATE TONIGHT.
REST OF THE FORECAST AREA WILL BE PARTLY CLOUDY TO MOSTLY CLEAR
SKIES OVERNIGHT. THERE WILL CONTINUE TO SOME RUNOFF ISSUES THROUGH
THIS EVENING FROM THE RAINFALL SO SEE HYDROLOGY SECTION BELOW FOR
MORE DETAILS. WINDY CONDITIONS ARE EXPECTED TO CONTINUE IN THE
KITTITAS VALLEY THROUGH THIS EVENING WHERE A WIND ADVISORY CONTINUES.

NEXT UPPER LEVEL LOW IN THE EASTERN PACIFIC WILL DROP DOWN THE COAST
AND TAKE UP A POSITION OFF THE COAST OF CALIFORNIA OVER THE NEXT
COUPLE OF DAYS. THIS WILL ALLOW A RIDGE OF HIGH PRESSURE OVER THE
GREAT BASIN TO BULGE UP INTO THE PACIFIC NORTHWEST RESULTING IN
MUCH WARMER TEMPERATURES GOING INTO THE WEEKEND AND DRY CONDITIONS.
THE UPPER LEVEL LOW WILL BEGIN TO MOVE INLAND LATE IN THE WEEKEND
WHICH COULD LEAD TO A CHANCE OF PRECIPITATION LATE SUNDAY MAINLY
OVER OREGON.

LONG TERM...SUNDAY NIGHT THROUGH THURSDAY...THE LATEST 12Z MODEL
RUNS HAVE COME INTO BETTER AGREEMENT OVER THE LONG TERM PERIOD. AS
THE LOW SPINS NORTHEASTWARD ON SUNDAY NIGHT AND MONDAY PRECIPITATION
WILL INCREASE...ESPECIALLY FROM CENTRAL OREGON THROUGH SOUTHEAST
WASHINGTON. THE ATMOSPHERE WILL BE UNSTABLE ON MONDAY...THEREFORE A
FEW THUNDERSTORMS MAY ALSO BE POSSIBLE. HAVE ADDED A SLIGHT CHANCE
OF THUNDERSTORMS AREAWIDE SINCE MORE PRECISE DETERMINATION OF
LOCATIONS OF STRONGER CONVECTION WILL ULTIMATELY BE DETERMINED BY
THE LOW TRACK AND THE AMOUNT OF DAYTIME HEATING AHEAD OF THE
RAIN...WHICH AT THIS POINT IS SOMEWHAT UNCERTAIN. THERE WILL BE A
BREAK IN ACTIVITY ON TUESDAY BUT SHOWERS COULD LINGER OVER THE
EASTERN MOUNTAINS. ANOTHER LOW IS THEN EXPECTED TO MOVE THROUGH THE
REGION ON WEDNESDAY BRINGING MORE RAIN. DRIER CONDITIONS MAY BE
POSSIBLE AGAIN ON THURSDAY IF THE LOW EXITS THE AREA QUICKLY
ENOUGH...YET IT IS MORE LIKELY THAT SHOWERS WILL CONTINUE.
TEMPERATURES WILL REMAIN SLIGHTLY ABOVE NORMAL ON MONDAY...BUT A
GRADUAL COOLING TREND WILL OCCUR THROUGH WEDNESDAY LOWERING HIGHS
5-10 DEGREES BELOW NORMAL.  TRIMARCO
